COMPONENT LOCATION
Information and Message Center - Overview
OVERVIEW
The message center is located in the instrument cluster, in a central position between speedometer and the tachometer.
The 5 inch Thin Film Transistor (TFT) display can be continually reconfigured to prioritize and refine the information presented to the driver.
The TFT screen displays vehicle related information to the driver, for example; engine temperature, fuel level, gear position, Terrain Response mode, cruise control and Hill Descent Control (HDC).
Driver information is also displayed, for example; navigation turn-by-turn information, voice control, trip computer information and basic audio details.
A main menu is available which allows the driver to change settings for vehicle set-up, trip computer and display settings.
Information and Message Center - System Operation and Component Description
System Operation
OPERATION
The information and messages which can be displayed in the instrument cluster are mainly generated from other system control modules. When a system control module detects a change or a fault which is tagged to generate a message, an electronic signal is sent via the medium or high speed CAN (controller area network) buses to the instrument cluster, which displays the message. If more than one message is requested the instrument cluster displays them in order of priority.
Component Description
DESCRIPTION
Odometer
The odometer is located in the bottom RH (right-hand) side of the message center. The odometer displays the total distance the vehicle has traveled. The trip computer readout replaces this when the driver requests trip information display.
Trip Computer
The trip computer memory stores data for a journey or series of journeys until it is reset to zero.
The following are available on the trip computer:
There are 3 independent trip recordings available to view; A, B and automatic. The instrument cluster main menu is used to select which trip recording is displayed. The A and B memories can be set independently, while the Auto trip will reset after every ignition cycle as the vehicle moves.
The automatic trip is always available and is reset each time the engine is started and the vehicle moves. Previous trips can be added to form a continuous trip recording by pressing and releasing the trip button on the end of the LH (left-hand) steering column multifunction switch when the automatic trip information is displayed. The message center will confirm that the previous journey information has been added and pressing and holding the trip button for 3 seconds will add the data. The previous trip information can also be deleted by pressing and releasing the trip button when the automatic trip information is displayed. The message center will confirm deletion of the previous journey data and pressing and holding the trip button for 3 seconds will delete the previous trip information.
Trip A and B can be reset by the driver at any time. When the required trip information is displayed, pressing and holding the trip button for 3 seconds will erase the previous trip information stored. Resetting trip A or B will not affect the other trip information, for example, if trip A is reset, trip B will retain its information until it is reset.
Ambient Temperature
The ambient temperature is displayed in the top RH side of the TFT screen. The temperature can be displayed in degrees F or C and this is selectable by the driver using the instrument cluster main menu.
If the external temperature falls to 4
